Apparently people can't read: OP is specifically asking for an email app that let you create folders.

Have you tested the other email apps on F-Droid?

My recommendations would be: use normal Firefox if that works for you, install uBlock Origin, enable Strict Tracking Protection in the settings, disable all the telemetry, enable the “AI kill switch” if you do not want any AI (including on-device translations) in your browser.

Projects like GrapheneOS and LineageOS strongly discourage rooting your device.

From my understanding rooting strongly reduces the security of the OS as it allows for exploits and privilege execution which would otherwise not have been possibly.

Rooting is also detectable by some apps, which will therefore block you from using them.

Strict Google Play Integrity can AFAIK not be spoofed with root on your device from my understanding.

Very on-topic: https://loops.video/v/gGFPxjD8Kz

It would be helpful if you would put in the title and description in which jurisdiction you live in.

As far as I remember, TrackerControl actually says that if it recognizes the app as a browser, the listed network connections are most likely from websites you visit.

Source? Also, some spaces do not allow politics; could that have been the reason?

Very reasonable stance.

Molly is no longer compatible with recent Signal updates, and the developers have stopped updating and monitoring Molly for some time now.

Please don't spread misinformation, you can easily verify that this is not the case:

You can setup a PIN, to prevent malicious usage.

TL;DR: Both; but it depends on your threat model who and what you want to protect against.
